SPECIFICATION forming part of Letters Patent No. 292,738, dated January 29, 1884.

' Application filed August 7, 1883. (No model.)

.To all whom, it may concern:

Be it known that I, JOHN EHRHARD'I, of St. Louis,`Missouri, have made a new and useful Improvement in Skylights, of which the following is a full, clear, and exact description, reference being had. to the annexed drawings', making part of this specification, in which- Figure 1 is a view inperspeotive of the improvement, the construction being shown in an unfinished condition Fig. 2, a4 vertical cross-section of the skylight-bar, the panes and cap not being shown; and Fig. 3, a vertical cross-section, including the panes and cap.

rEhe same 'letters of reference denote the same parts.

This improvement has relation to the skylight-bar, and the mode of closing the joints between the panes and the bar.

A A represent the panes.

B Bv represent the skylight-bar, the bar being composed of plates, which are extended vertically at b b, bent at b b', respectively, and extended outward and upward at b2,bent again, and extended horizontally farther outward at b3, bent again, and extended upward and outward to thepoint b4, at whichlast-named point the plates are each folded and turned back, and inward to the point b2. From this last-named point the plates are extended upward and inward to the point b5,tl1ence directly upward to the point b6,thence folded and extended downward to the point b5, thencehorizontally ontward to the point b?, and thence upward, as shown. In this manner two gutters, C C, are

formed in the bar, which receive the moisture entering between the edges a a of the panes and the plates b b. Two outer auxiliary gutters, DD, are also formed in the bar, and above l the gutters D D spaces E E are provided for the packing-strips F F, which are preferably 4o of rubber. The panes rest upon the strips F F, and at their inner edges, a a, the panes abut against or come into immediate proximity to the plates'b b, respectively. The cap G is secured to thebar by means of the strips 45 g g, which in turn are fastened to the bar by means of the rivets H. These rivets H also serve to connect the plates b b. The cap extends downward, at either side of the bar, t'o

the panes A A. The panes are sustained by 5o the packingstrips F F, which in turn4 and vas stated are held at E E in the extensions of the platesb b, To prevent these extensions from spreading apart-that is, opening away from the plates b b-the ties I I are extended 55 from the plates b b totheextensionsin the vicinity of the grooves E E. Y I

The strips I I are suitably s'paced apart to enable the moisture entering between the panes and the plates b b to pass downward 6o into the gutters C C.

I claiml The combination of the panes A A, the plates B B, bent to form the gutters C G vand D D and the grooves E E, the packing-strips 65 F F, and the cap G, the strips g g, secured to the plates B B, and the ties I I, whereby double gutters are afforded as well as a free space for the descent ofthe moisture between the packing and the skylight-bar plates, substantially 7o
